Summary of MARVELL TECHNOLOGY GROUP LTD

Item 1.01 Entry into a Material Definitive Agreement.

On October 22, 2009, the Board of Directors of Marvell Technology Group Ltd. ("Marvell"), approved an amendment and restatement of Marvell's Amended 2000 Employee Stock Purchase Plan (the "ESPP"). Under the amended and restated ESPP (the "Restated ESPP"), the "look-back" period for the stock purchase price will be changed from 24 months to six months. Thus, participants will have the option of deferring a percentage of compensation into the plan for a six-month period beginning either December 8 or June 8 of each calendar year and purchase Marvell common shares with such deferred amounts at a price that is 85% of the lower of the fair market value of Marvell common shares at the beginning or the end of said six-month period.

Pursuant to the terms of the Restated ESPP, the existing 24-month look-back periods will be phased out so any currently enrolled participant in a current 24-month offering period will continue in the current offering period until the earlier of the end of the offering period or in the event the current offering period is reset. A reset occurs if the fair market value of Marvell common shares on any purchase date is less than it was on the first day of the offering period. All eligible employees will be subject to the six-month look-back periods no later than the offering period beginning in June 2011.

Participants enrolled in the new six-month look-back periods will no longer be subject to a limitation on the number of shares that may be purchased in the event that the market price of Marvell's common shares decreases by more than 25% from one purchase date to the next. This share limitation was triggered in connection with the June 2008 purchase period, which ended in December 2008, and continues to apply to current participants enrolled in a 24-month look-back period pursuant to the terms of the Restated ESPP. A participant's right to purchase shares is still subject to certain limitations specified under U.S. tax law. A participant may only make purchases pursuant to the Restated ESPP at a maximum market value of $25,000 in any calendar year. The market value of Marvell shares used in computing the $25,000 maximum market value at the time the ESPP purchase right is granted. In addition, a participant may purchase no more than 7,500 shares per six-month offering period.

There was no change to the total number of shares available for purchase under the ESPP. All employees, including executive officers, are generally eligible to participate in the plan, subject to limits set by the Internal Revenue Code. The Restated ESPP became effective on October 22, 2009. The foregoing description of changes to the ESPP is qualified in its entirety by reference to the Restated ESPP, which is attached hereto as Exhibit 10.1.
